ELECTRICAL CONNECTION

Take care !
Before starting any electrical connection, check
that the electrical supply corresponds to the
specification indicated on the unit's maker's

supplied with hot water in winter or with chilled water in
summer and during the mid season periods. A 3-way
valve must be installed on the water circuit
supplying the unit.
Summer and mid-season: The 3 way valve is controlled
by the thermostat to obtain cooling.
Winter: The 3 way valve is controlled by the thermostat
to obtain heating.

2. Fit the thermostat on the water inlet pipe.
3. Cover the connection with a protective sheath.

WATER TEMPERATURE PROBE INSTALLATION

The SW probe supplied in the unit is to be located on
the water inlet pipe.

e
lectrical connection
The manufacturer and their representatives decline all
responsibility for any accidents caused by inadequate or
non-existent earthing of the installation.
All the cassettes are intended to operate on a normal
voltage of 230V ± 10% / 1 phase / 50Hz + Earth or
3N~400V ± 10% / 50Hz.
The wiring diagram affixed to the unit illustrates the
connections to be made.
A device to disconnect all the power conductors
with an approved minimum opening distance
must be included in the mains power supply
according to best installation practices.
CHANGE OVER SENSOR
The change over sensor supplied in the unit is to be
located on the water inlet pipe. It enables the thermostat
action to be reversed in relation to water temperature.
